SPBAYER ATTACHMENT FOR FU RNACES.

' Application filed May 25,

To all whom it may concern:

Be it known that I, GEORGE l-I. CLEMEN'rs, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sprayer i'ittachments for Furnaces, of which the following is a specification.

My invention relates to attachments to furnaces and has special reference to devices for preventing the escape of the liner particles of the ashes when the grate is shaken.

The tendency of the ash dust to become diffused outside of the ash-box during the process of shaking a grate where coal is burned for fuel is a-matter of common observation, and the disagrccableness of the procedure as well as detriment to the health when breathed into the lungs render any method of avoiding such results very desirable. In addition to this disposition of the line dust thus produced to fill thesurroinnling air when the grate is agitated, the process of removing the ashes from the box even when a sufficient time has been allowed to elapse after the agitation to permit the dust to settle will again cause the ashes to be raised in disagreeable quantities. As hard coal does not require a very heavy draft in order to promote combustion, the natural draft of the chimney will not be sufficient to carry all the dust up the flue, especially as the times during which it is necessary to resort to the cleaning and shaking process is when the ire is low from the clogging of the grate.

The chief objects of my invention are to provide means for preventing the escape of fine ashes when the grate ot' a furnace is shaken by thoroughly mixing a fine spray of water with the ashes during the agitation of the grate; to produce a simple device for the purpose stated that can be applied to any furnace; and to supply an efficient apparatus for dampening the ashes after they have been shaken down.

Further objects of my invention are to produce a device for the purpose in view that can be constructed with ordinary tools and Without the necessity of special machinery and enable the device to be put on the market at a minimum price.

I accomplish the above objects by the use of the appliance illustrated in the accom-' panying drawing which forms a part of this specification and in which Figure 118 a side view of my improved ash Specification of Letters Patent.

I sprinkler showing the method of attaching it to a furnace, only so much of the latter being shown will sullice to show their relation; Fig. 2 is a plan view taken on the l 2-2 of Fig. 1; Fig. 3 is a sectional elevation of the sprinkling device alone taken in a plane transverse to the perforated pipes.

Referring to the drawing in detail the numcral it) indicates the fire pot of a heating furnace, 12 the ash pit. and 11 the flange or ledge which forms a division between the two and serves as a support for a cross bar 13 u )Oll which is carried a grate 14 of the usual form and capable of being rotated and dumped in the ordinary way.

A semi circular pipe formed of two segments 1:). 16, rests upon the ledge 12 externally to said grate and lyin below the level of the rotary portion 14 of t 1e grate, and the arc thus formed is joined at its extremities by a straight section 17, which forms the chord of the are or semicircle and is joined to said arc by elbows 1S. 1 The said segments 15, 16, are. connected by a tee coupling 19, to which is attached a short horizontal pi e 20 which extends at any convenient aiige from said tee, and msscs through an aperture 20" in the wall of the wt 10 and is joined to an upwardly curved fpi e 21 by a coupling 21 .the upper end 0 tie pipe 21 terminating in :1 cy indrical reservoir 22, which is shown open in the drawing but which may be furnished with a cover, and may be of any desired size and shape.

The coupling 21 is )rovided with a valve .23 by means of which the water may be turned on or oil' at will.

The pipes forming the are, 15, 16, and the chord pipe 17 are supplied with a series of orifices 24. 'lhcsc opcnings are of comparativcly small caliber and I prefer to locate them somewhat downward from the horizontal plane of the segment so that the jets which issue therefrom, may be deflected so as not to strike the grate or reach the hot coals which may lie above. I also find it desirable to make these orifices in the shape of clung-aged slots with their long diameters lengthwise of the ipes thus tending to spread the liquid in tun films-rather than in coarser jets as conducing to a better result. l The method of using my ash sprinkling appliance is as follows: The device having been attached to a furnace iii-the manner shown, which it will be observed docs not interfere with the operation of the grate either in proceeds to shake down the ashes, at the devices of my invention as herein disclosed senses shaking or dumping, and the requisite quantity of water placed in the reservoir 22, the stop cook or valve 23 being previously closed, the operator willIapply the bar or wrench to the grate in readiness to shake it to get rid of the ashes. Before doing this he turns on the water at the valve 23 and immediately same time the Water, -lilling the connecting pipes be forced out o f the orifices 24 to mingle in a fine spray with the ashes as they fall through the grate. In this Way the Water is thoroughly mixed with the ashes and the uantity of moisture may be regulated by tie valve 23 as to give the required results and avoiding an unnecessary wetting of the refuse which would make it disagreeable to handle for removal.

It is evident that the reservoir may be located at a greater height in order to obtain more pressure, or the pi e 21 could be connected with any source or supply besides that shown and other changes may be made in the without departing from the spirit and scope i thereof and I do not wish, therefore, to be limited to the precise construction set forth.

Having thus described my invention What I claim as new, is

In combination with a furnace ash-box having an inwardly projecting lodge below the grate, a sprinkling device consisting of a perforated bent pipe extending part nay around said ash. box and supported on said ledge, a perforated straight pipe connecting on the ends of the bent pi )e, a water supply pipe connected with said bent )ipe and ex tending externally of said ash-lion, a manually operable valve arranged in said pipe, and means for supplying water to said supply pipe, said means consisting of a reservoir connected with the supply pi e and arranged adiacent to the fnrnac n testimony whereof I aflix my signature in the presenc" of two VIIIN-FSGr enonen n we JMENTS.
